BRACKET FOR CLOTH RADIATOR CVERS.

Appication filed January 6, 1923. Serial No. 611,074.

To all whom t may concern Be it known that l, AUGUST F. Herzen, acitizen of the United States, residing at Ann Arbor, in the county ofWashtenaw and State of Michigan, have invented new and nsefuiimprovements in Brackets for Cloth Radiator Covers, of which thefollowing is a. specification.

This invention. relates to covers for the radiators of heating systems,and more particularly to brackets for supporting cloth covers thereon.

The primarj)7 object of this invention resides in the provision of meansfor supporting cloth covers, over the radiators of heating systems, sothey will be retained in taut condition out of contact'. with the coilsof the radiators.

Another object of this invention resides in the provision of means forsup-porting double cloth covers in taut condition over a predeterminedarea of the coils of radiators for heating systems.

A fur-ther object of this invention resides in the provision of aycertain combination of coacting elements adapted to be contracted forreceiving a cloth cover, for a heat radiator, prior to being released toreA tain the cover in taut condition over the radiator.

A stili further object of this invention resides in the provision ofparticularly formed brackets which are capable of rigidly supportingcloth covers, over heat radiators, so they can be readily removedwithout displacing the. bracket.

With these and other objects in view, this invention resides in certainnovel features of construction, arrangement of parts and combination ofelements to be hereinafter more particularly set forth in thespecification, illustrated in the accompanying drawings and pointed outin the appended claims.

In the accompanying drawings:

Fig. 1 is a front view of a portion of a heat radiator showing a doublecloth cover in operative position thereover.

Fig. 2 is a front view of a` portion of a heat radiator showing theelements of this invention secured in operative position on the radiatorwith the cloth cover removed.

Fig. 3 is a side view of the elements of this invention as disposed inFig. 1.

Fig. i is a detail perspective View of a portion of one of the bracketsshowing one of the spring clips thereon.

Fig. is a longitudinal sectional view of one of the guide blocks for thebrackets.

Fig. 6 is a 'detail view of a portion of a radiator showing one of thesupporting brackets contracted for receiving thc cloth cover.

Fig. 7 is a detail perspective view of one of the supporting bracketsper se.

Fig. 8 is a detail perspective view partly in section of one form ofcloth cover employed in conjul'lction with the elements of thisinvention.

Fig. 9 isa detail perspective view of one of the guide blocks.

Fig. 10 is a perspective view of one of the U-shaped yokes.

n the present embodiment of this inventionthe letter R designates aconventional illustration of a radiator of heating systems.

Suitably secured to the radiator R as at 5 are guide blocks 6 which areprovided with spaced ears 7 having apertures 8 therein for -slidablyretaining the supliorting brackets to be hereinafter set forth. Whilethe aforesaid guide blocks (i may be rigidly secured to the radiators inany suitable manner, the present disclosure employs U-shaped yokes 9adapted to straddle the connecting tubes T of the radiators with theirfree ends extending through apertured lugs 11 on the guide blocks forreceiving nuts or thumb-screws 12. In order to prevent the blocks frommoving, after the nuts or thumb-screws have been tightened, the undersides of the blocks are provided with serrations 13 for engagement withthe contacting portions of the radiators.

Each cloth supporting bracket is preferably formed from a single pieceof heavy `wire bent upon itself as at 111 and extended in parallelism asindicated at 15, whereupon the cloth receiving arm 16 thereof is archeda convenient distance above and beyond the supporting arm 17 thereof.The supporting arm 17 of each bracket is bent substantially at rightangles to the arched portion thereof and is provided with apertures 19and 20, for purposes to be hereinafter set forth.

Each bracket is supported by its companion guide block through theinstrumentality of the ears 7 and its arm 17, and is retained inlaterally yieldable relation with `the supporting blockthereof throughthe provision of an expansible coil spring'` 18 adapted to bear againstone of the ears 7 and a Washer 20 which bears against a stop pin 21passing through the aperture 19 in the arm 17.

In order to steady the looped end of each bracket and secure therigidity of said portion a frictional leaf spring 22 is attached to oneof the parallel branches of the bracket and extended in contact with oneof the coils of the radiator, whereupon the looped end of each bracketwill be yieldably retained between the radiator and the Wall W of thebuilding.

l/Vhile fabric covers of various types may be conveniently employed inconjunction with the particular brackets herein set forth, the presentdisclosure employs what is termed a double cover type, the same beingdesignated 23. rlhis particular type of cover consists of' a sheet offabric having three of its edges secured or stitched and one edge openso that the same can be slipped over the supporting portions 17 of thebrackets.

To facilitate placing the cover over the brackets, the distance betweenthe supporting portions thereof is shortened by compressing the coilsprings until the apertures 2O are exposed beyond the outer sides of theears 7 'whereupon pinsare inserted therein to retain the brackets incontracted condition. After the cover has been properly assembled, thepins are removed, whereupon the brackets Will be ejected laterally inopposite directions by the springs until checked by the bound sides ofthe cover, thus resulting in the cover being stretched.

"With this invention fully set forth, it is manifest that means havebeen provided for readily supporting cloth covers over heat radiators sothat the supports at both ends Leisure may be cont 'acted for assemblingthe cloth on the brackets, but it is to be understood that the right isreserved to employ one slationary bracket and one yicldable bracketinstead of similar brackets as herein disclosed.

Having thus described this invention what I claim and desire to protectby Letters Pat ent is 1. The combination with a heat radiator, of a`pliable cloth cover, stationary guide blocks secured to the radiator,cover supporting brackets slidably supported by the stationary guideblocks, yieldable means between the guide blocks and supporting bracketsfor stretching the cloth cover and frietiona'i clips carried by thebrackets re mote from the yieldablc means therefor.

The combination with a heat radiator, of a pliable double cloth cover,guide blocks in spaced relation on the radiator, a yoke binding eachguide block to the radiator, brackets slidably engaged by the guideblocks and supporting the cover, and means for yieldingly supporting thebrackets on the guide blocks.

3. The combination with a heat radiator of guide blocks secured inspaced relation thereon, apertured ears on said guide blocks,securingmeans between the adiator and guide blocks, brackets havingsupporting arms slidably engaged by the ears of the guide blocks,Washers lixcd on the slid-able arms of the brackets and disposed betweenthe ears of the guide blocks, expansion coil springs on the supportingarms of the brackets between the Washers and certain of the ears on theguide blocks, and frictional clips carried by the brackets in contactwith the radiator.

ln testimony whereof I atiix my signature.

AUGUST F. HUTZEL.
